Adopted LoRa (Long Range) protocol and realizing receiving and transmitting in one single module, the U70 datalink module can reach more than 10km working range while keeps the transmitting power at 2W and the receiving power at 0.2W. The ultra-long working range brings more possibilities for wider applications.
Featured surface-mounted design, 30×30×3mm small size and low power, the U70 module is specially designed for system developers. With good electromagnetic compatibility, U70 can be integrated in GNSS related applications, such as land surveying, precise agriculture and other unmanned systems.
With advantages of stable output power, high receiving sensitivity, low error rate and strong anti-interference ability, the U70 shows strong performance for real-time data transmission. The advanced CSS digital modulation technology and demodulation technology, making it suitable for RTK application.
